Abstract
An electronic apparatus is disclosed. The electronic apparatus includes: a microphone, an IC chip configured to, based on a level of a user voice received through the microphone being equal to or greater than a threshold value set as a first level, identify whether the user voice includes a wake-up-word (WUW), and a processor configured to, based on the WUW being included in the user voice, transmit a signal corresponding to the user voice to an external electronic apparatus, and based on the transmitting of the signal corresponding to the user voice being completed, set the threshold value as a second level lower than the first level, wherein the IC chip is configured to, based on a subsequent user voice being received through the microphone, identify whether a level of the subsequent user voice is equal to or greater than the threshold value set as the second level, and based on the level of the subsequent user voice being equal to or greater than the threshold value set as the second level, identify whether the subsequent user voice includes the WUW.
